    Thanks for doing a build with the proposed patches. They seem to have
    solved the issues on kfreebsd and the hurd port builds again (but still
    fails one testcase). I have pushed the commits below to master.
    The only thing that worries me is the sparc failure. I have CCed Jose
    who might want to take a look. What is strange is that 0.165-1 and
    0.165-2 PASS on sparc just fine. And I don't see anything in 0.165-3
    that would explain the failure on sparc:

The problem seems to be:

/«PKGBUILDDIR»/tests/backtrace: dwfl_thread_getframes: No DWARF information found

and that is probably triggered by this code in __libdwfl_frame_unwind:

Dwfl_Module *mod = INTUSE(dwfl_addrmodule) (state->thread->process->dwfl, pc);
if (mod == NULL)
  __libdwfl_seterrno (DWFL_E_NO_DWARF);

I definitely can't reproduce this problem in my own sparc64-*-* setups.
